意见分歧特征下多评价结论协商组合方法

针对多属性综合评价中存在的“多方法评价结论非一致性”问题,提出了一种意见分歧特征下的多评价结论协商组合方法.首先,获取评价双方的协商信息,建立基于协商点总偏差最小的二次规划模型,然后用求得的最佳协商点对方案进行排序.该方法具有协调分歧意见,集成评价者(或决策者)知识经验,优化评价结论等特点.算例验证了该方法的有效性.

Combination Bargaining Method for Multi-Evaluation Conclusions Characterized by Disagreement

Disagreements between the conclusions drawn by different evaluation methods are often found in multi-attribute evaluation.A bargaining combination method is therefore proposed to deal with the multi-evaluation conclusions characterized by disagreement.With the information on bargaining obtained from both evaluation parties,a quadratic programming model based on the minimized total deviation at bargaining points is developed,then the different projects are ranked using the optimal bargaining point picked out.The method has advantages such as coordinating disagreements,integrating the knowledge of evaluators or decision-makers and optimizing evaluation conclusions.A numerical example is given to verify the effectiveness of the proposed method.
